From f3c5fe979117908fb642ed130ae2cd78cb005931 Mon Sep 17 00:00:00 2001 From: Wei Yongjun Date: Mon, 16 Dec 2013 14:13:25 +0800 Subject: [PATCH] drm/i915: fix return value check of debugfs_create_file() In case of error, the function debugfs_create_file() returns NULL pointer not ERR_PTR() if debugfs is enabled. The IS_ERR() test in the return value check should be replaced with NULL test.
